APPLICATION FILED JULY2s,191m

`systems and has for its object the Uiarrnn sTAT'Es rafrnnr enrich.

Chicago, county of Cook, and State of Illi-I nois, have invented certain new and useful `Improvements in Lawn-Sprinkling Systems, of which the following is a specification.

My invention relates to lawn sprinkling roduction of a system of this character whlch will bel Yautomatic in its operation, of' durable and economical construction, and which will be of great efficiency. F

Other objects will appear hereinafter. u

With these objects in view my invention consists in a lawn sprinkling system char.

acterized as above mentionedand in certain details of construction and arrangement of parts all as well be hereinafter fully described and more particularly polnted out 1n Vthe appended claims.

My invention will be more readily undp/r3 stood by reference to ,the accompanylng drawing .forming a part of this specification,

in which, n

Figure 1 is afsectional view of a lawn and a portion .of a house adjacent-ly located to which is applied a sprinkling system embodying the preferred form ofmy invention, Fig. 2 is an enlarged-central longitudinal section of a controlling valve included in the system, the section being taken on line .fcof Fig. 3, and Fig. 3 is a transverse section taken on line g/I-g/ of Fig. 2.

lReferring now to the drawing, 1 designates the lawn to be sprinkled and 2 ra dwelling house adjoining the lawn, 3 indicating the basement of lsaid house, the dwelling floor being shown at 4l. Extending from said basement is a plurality of water pipes 5 which are buried in the ground beneath the lawn, said pipes being of various lengths so that the same terminate at their outer ends below various points in the lawn. At t-he outer extremities of the pipes 5 are provided vertically extending exteriorly projecting pipe sections 6, at the upper extremities of which are provided spraying` nozzles 7 of any well known type. At their inner eX- tremities the pipes 5 are connected to a Valve 8 the function of which is to govern the flow of water to said pipes so as to effect the admission of water thereto successively. Said valve is arranged Within the basement Specicat'ion of Letters Patent. application med July 2s, 1910.` 'serial No. 574,369;

openings 13, the outer Patenten oca 3, 191i..

3, the same being mounted upon a suitable bracket 9. nSaid Valve comprises an outer cylindrical casing-16 open at one end, the op- .l posite end thereof being apertured and nippled as at 1 1 for the connection of the water supplypipe 12 thereto, water under pressure being supplied through the latter.`

In the lateral wall portion of said casing is provided a pluralityof spaced discharge l ends of said openings b elng provlded w1th nipples for the connectlon .ofthe pipes 5 thereto. Snugly fitted w1t h1n the casing 10 is a rotatable Vhollow cylinder 14, the end thereof registering with the opening 1l in the casing 10 being open for the admission of `water thereto. Said member 14 is held in position in the casing 10 by means of a head- 15 4threaded upon the open end of the latter.v Said'head is centrally apertured for the passage ofa stem 16 projecting centrally from the adjacent head of the member 14, an arm 16 rigidly attached to said stem ali'ording means for ready rotation ofv the member 14. In t-he lateral wall of the latter is provided a plurality of circumferentially elongated slots 17 so positioned therein that when the member 14 isrot'ated said slots will be adapted to register with the openings 13 in the casing 10. Said slots are, as seen, radially spaced in the member 14 so that, when the latter is rotated as above mentioned, the former will be successively brought to register with the openings i 13, the arrangement being such that, when anyone of said slots is in registration with its discharge opening 13, the remainder of the openings 13 will be closed by the lateral wall of the member 14. The side of the latter opposite t-he slots 17 is cut away as at 18-'so that'with water under pressure in the valve, as when the device is in operation, pressure will be ybrought to bear by the water more strongly upon the slotted side of said member to force the same into close engagement with the adjacent wall of the casing 10 and thereby prevent-leakage between said walls.

Arranged upon a .bracket 19 positioned below. the valve 8 is a water pan 20.- A

cock 21 controls a discharge opening at the lower end of said pan, said cock permitting discharge from the pan 20 to a recepetacle 22 arranged below the same. Vertically movable in the pan 20 is a float- 23 which is connected to the free end of the arm 16 bya cord 24, the latter passing over a roller 25 carried in a projection 2G formed integral with the bracket 9. A cord 27 secured at its lower end to the tree end of the arm 16 extends upwardly therefrom through the floor 4 for connection with a lingered bracket 28 whereby said cord may h be supported at diii'erent elevations.

Theoperation of the system is as follows: The pan 20 is first filled with water to a level at which the water will buoy up the fion-t 23 to a height at which. the first of the slots 17 will just be in registration with the discharge opening 13 eo-acting therewith, suoli position thereot` being clearly shown in Fig. lVater under pressure is then ad init-ted through the pipe 12 to the valve S and the water in the pan 20 is permitted to drain slowly through the cock 21 to the receptacle 22, the upper end of the cord 27 being, in .this operation, supported at its lowermost posit-ion so as to permit of free downward movement of the arm 1G. lith this arrangement it will be seen that as the pan 20 drains, effecting the gradual lowering of the surface or level of the water therein and hence of the position of the lioat therein, the arm 16 will be rocked downwardly. Such rocking of the arm 1G obviously eliects the bringing lof the slots 17 successively into registration with the Vvarious discharge openings 13. Thus water lin the event of the tioat mechanism becoming disabled, or where it is desired perhaps to sprinkle certain sections of the lawn more thoroughly than others, since with this arrangement the member 14 may be held in. one position any length of time, to

change the position thereof it requiring only to engage said cord withv a lower or higher hook, as the case maybe, in the rack 28.

While I have shown what I deem to be the preferable form of my sprinkling system I do not wish to be limited thereto as there might be various changes made in the details of construction and arrangement of parts described without departing from the spirit of the invention comprehended Within the scope of the appended claims.

IIa-ving described my invention what I claim as new and desire to secure by Letters Patent is:

l. In a lawn sprinkling system, the cornbiiiation with a lawn, an adjoining dwelling house, und a source of water supply, oi' a plurality of pipes buried in said lawn the outer extremities thereof terminating so as to adapt the same to spray water over varions sections of said lawn, a valve ar- Y ranged in said house, the same communicating with said source of water supply'and controlling the fiow ot' water to. said pipes said valve being. adapted to successively establish communication between said pipes and Said source of water supply, and automatic and manually operable means for o erating said valve, substantially as escribed.

2. In a lawn sprinkling system, the combination with a lawn, an adjoinin'g dwelling house, and a source of water supply, of a plurality of pipes buried in said ,lawn the outer-extremities thereof terminating so as to adapt the same to spray water over vaiious sections of said lawn, a valve arranged LOUIS D.
